Black and White Aerial Photos were used in teh early part on the 20th century. This type of mapping is raster imaging. The image above from the New Zealand Electronic Text Centre shows part of the dock area at Dunkirk where the German invasion fleet was concentrated. Dock buildings round the upper of the two docks shown have been completely destroyed and unloading cranes smashed. Damaged barges can be seen near the entrance of the upper dock where a number of others have been sunk.
